.vented certain new and useful improvements in Goggles, of which the following is a full clear. and exact description.

This invention relates to goggles which are used by :iutomobihsts and tier persons desiring to protect the eyes from dust. dirt, and other foreign matter.

lhe oh ectof the invention is to provide a goggle, the parts of which may be readily usseinlxled, will maintain the transparent [121K185 orlcnses firmly in place, and per mit these panes or lenses to he removed or replaced with the greatest ease and facility. *With this and other objects in view the invention consists in making each eye-piece of the goggle in separate sections, nrnnely, lens rim kind on eye-cup,; in providing a locking joint between these parts whirl will hold them against inadvertent separation, and inproviding part or parts carl-ied by he eye-cup which are adapted to hear against the lens or transparent pane to firmly hold it within the lens rim after th eye-cup has been locked to the rim.

The character of the invention may also he understood by reference to the following description of an illustrated embodiment thereof snown in the accompanying drztW- ings. whcrein' Figure l is a top view of a pair of goggles embodying the principles of the. invention; Fig. 2 1S a detail view of the lens rim; Fig. 3 is a detail view of the eyecup, and Fig. 4 is a longitudinal section showing the construction by virtue of which the lens is held in position within the rim. Fig. 5 is a transverse section showing the same construction and G is 21 detail showing the pro'ecting log on the eye or cap.

The goggles shown herein a the invention comprise. two eye-nieces l "3, which may he connected by n i which serves as a bridge, althougn a. rigid bridge may be used it desired. l lnch eyepiece consists of a lcns rim el, 1 ferahly formed of sheet metal and consis of a ring having an inturncd flange which forms a seat for a lens or transparent pane I of any desired character.

The eye-cup is formed from a separate iiece of sheet metalandjis designated 8. It is of the usual shape and has the'edge which bears against the face of the. wearer pr o tected by padding- 01 cushion 9 of leather or other suitable material. Straps or hands 10 of elastic materialare secured to the eye-cups and are adapted to pass around the head of the wearer to hold the goggles in place. Ventilating openings may be provided in the eye cup preferably by cutting U-shaped slits in the-metal and by slightly offsetting the lips 12 which are thus formed. The cuts should be made so that the lips extend rearwardiy to prevent the passage of dirt or dust into the interior of lhc'cup.

According to my invention the lens-rim and eyecup are united'by a locking joint which will hold the parts securelytogether and will prevent their inadvertent separa tion while permitting them to be separated at will when necess try- Various locking joints which will perform thisfunction may be used. A bayonet joint has been found suitable in practice nnd awspe'cificembodiment of this type of joint will be described. inwardly projecting protuberances llere formed upon the lens-rim by indenting the ring 5 adjacent its peripheral edge which is remote from the flange 6. The eye-cup is provided with a sleeve 13 of reduced diameter which is adapted to fit snugly 'withi-n the ring 5 and bayonet shaped grooves 14 are punched or otherwise formed in this sleeve which tiresuitably spaced to engage with the'protuberances 12. In order to prevcnt inadvertent rotation of the eyecup relative to the lens-rim which might result in the separation of the parts, holes or 21 perturcs 15 are. formed at the inner ends of the bayonet grooves and the protuberantes 1-2 lit into these apertures when the parts are properly assembled whereby the protiiheran cs will engage the walls of these apertures and preventinadvertent rotation of these. ports. If, however, a positive force is applied to cause a relative rotation of the lens and eye cup, the sleeve will yield permitting the protuberance to again enter the h vonet groove after which the parts may in easily separated.

The lens or transparent pane 7 which is mounted in the lens rim rests against the or flungv G where it is firmly held in place by lugs or fingers 16 which projecterably bent slightly inwardly before they parts are assembled, and after the eye-cup .and lens rim have been locked together the fingers or lugs are then pressed into engageiment with the lens or glass to'thereby force it against its seat. This istruction is also of-lmportance because a yonetor like JOll'lt between the eye-cup and lens rim does not permitof the-agial adj ustment of these parts;

by making the lugs or fingers semi-flexible as described, thesedingers may be'bent into' engagement with a lens of any desired thickness and hold it firmly in place within the 4 lens rim. If it is necessary to removethe lens, the eye-cup or lens rim may be separated at will and the lens rim will then be free to be removed. It will therefore be seen that by the construction described the parts of the eye-piece including the lens may be' readily assembled '-'or disassembled, and yet when the parts are united each one is rigidly held in its correct position Without any danger of inadvertently becoming loose or separating from the other parts j I claim: i

1.;In.-a gogg le construction, an eye-piece.

comprising a lens rim, :1 lens in said lens rim, a flange ons'aid rim againstwhich said lens is 'adaptedto rest, an eye-cup,'a locking joint between said lens-rim and eye-cup, and

.'a plurality; of semi-flexible fingers carried bjgfsaid eye-cup adapted to be bent tobear against said lens to hold it against its flange 1,201 ,ose'

when the eye-cup and lens rim are locked locking joint between said sleeve and said lens rim' and a plurality of semi-flexible fingers carried by the'eye-cup adapted to be bent to press against the lens to maintain it against its flange whenthe eye-cup is-locked to the lens rim.

3. In a goggle construction, an eye-piece comprising a lens rim and an eye-cup, said lens rim having a flange, a lens in said r-im resting against said flange, a sleeve on' said eye-cup fitting into said rim, a bayonet joint between saidsleeve and said lens rim, apertures in one of said parts forming a continuation of the bayonet grooves formed thereon, protuberances on the other part of the bayonet joint fitting into said apertures when the eye-cup is lockedvto the lens rim, and a plurality of fingers carried by the eyecup adapted to bear against the lens and hold it in position against the flange when the eye-cup is locked to the lens rim.

4. In a goggle construction, an eye-piece comprising an eye-cup and a lens rim, a

locking joint between these parts preventing axial adjustment thereof, a lens in said rim, and semi-flexible fingers carried by said eyecup adapted to be bent into engagement with the lens and maintain it in position in the lens-rim.
